Abstract (en)

[origin: EP1138916A2] The method involves increasing or reducing the drive voltage depending on the operating conditions of the injection valve. Past offset values for the drive voltage are stored, the highest and lowest (Mx, Mn) are selected and used to form a maximum bandwidth for the offset values that remains available for subsequent operation and any required adaptation of the drive voltage.
